Evaluate<br> 5-(2w-8)=6w-9

Brilliant_brown [7]

Step-by-step explanation:

Steps

5−(2w−8)=6w−9

Show Steps

Expand 5−(2w−8): −2w+13

−2w+13=6w−9

Subtract 13 from both sides

−2w+13−13=6w−9−13

Simplify

−2w=6w−22

Subtract 6w from both sides

−2w−6w=6w−22−6w

Simplify

−8w=−22

Divide both sides by −8

−8w

−8 =

−22
